PC - P3 800MHz with 256Mb and Nvidia GeForce FX5200 (128Mbb)
Distro in use - Ubuntu
I posted this on Ubuntu forums but it seem it's a common problem with no answers so hopefully one you guys might know better
I had Warty with XFree86 - nvidia driver was installed from apt-get successful, OpenGL applications worked fine.
Move a window in xGnome however take up to 80% CPU resources according to top. (xorg)
As a result Gnome isn't fun to use, you can see windows being redrawn etc (I have 2nd PC with Windows XP) and I wanted to use Ubuntu as my work machine, but I keep going back to Windows since it does have a much more snappy feel to the GUI!
Later on I have updated my Ubuntu system to the Hoary (change Warty to Hoary in res in Synaptic Package Manager) and updated everything using Smart update. and rebooted.
Then I installed xorg and uninstalled XFree86 and rebooted - I am now running Ubuntu Hoary with xorg and the Nvidia driver is running fine without needing to configy the xorg.conf file.
OpenGL applications still fine.
Move a window in Gnome still suck up 70% CPU and so it slows down the whole system to the point that it's just silly.
In Windows you can have the card render the windows and so on - which gives it a very snappy fieel.
Can you do the same thing in Xorg so that the card is doing the work NOT the CPU?? If so, how do I do that? And don't someone dare tell me to read the readme file from nvidia - this I have done and it does not help an iota.
This problem of xorg/xfree taking up large amount of CPU is ruining what is a otherwise fantastic Linux distro and from reading in here it seem I'm not isolated If someone have a solution, please post and it should be made sticky
